Abstract

Provide is a close cavity semi-spherical surface lighting and spotlight multiplication solar water heater. The device receives solar energy through a reflect light focusing effect of a revolution paraboloid, the receiving efficiency of the solar energy is greatly improved, solar energy collecting and receiving under hard light and weak light environments are achieved.

Description

Technical field: [0001] The invention relates to a solar energy application technology, in particular to a closed cavity hemispherical surface daylighting and concentrating multiplication solar water heater which utilizes the principle of concentrating light of a rotating parabola to receive solar energy. receiving efficiency. Background technique: [0002] Solar energy is a kind of clean energy, inexhaustible and inexhaustible, and will not cause environmental pollution. Nowadays, whether in coastal cities or inland cities, solar energy products are increasingly entering people's field of vision. Solar street lights, solar lawn lights, solar garden lights, solar corridor lights, bus station lights, traffic lights, etc., all kinds of solar water heaters have also approached thousands of households. However, most of these solar products do not have the function of concentrating light, resulting in low utilization of solar energy. If the light intensity on the surface of the...
